Having failed to find in books a satisfactory theory of those conditions 

 which produce lateral cumatitre, Mr. Harwell resolved to investi- 

 gate the subject for himself ab initio. The present work is the 

 result of long and patient study of Spines, normal and abnormal. 

 He believes the vievus which he has been led to form account for those 

 essential characteristics vuhich have hitherto been left unexplained ; 

 and the treatment which he advocates is certainly less irksome, and 

 will be found more efficacious than that which has hitherto been 

 pursued. Indeed, the mode in vu/iich the first edition has been 

 received by the profession is a gratifying sign that Mr. Barvoelfs 

 principles Jiave made their value and their weight felt. Many 

 pages and a number of woodcuts have been added to the Second 

 Edition.
